NEC handed out datasheets for a new (but as yet unannounced) chip in its “VR Series” system-on-chip (SOC) processor product line, at this week's Embedded Processor Forum in San Jose, CA. The VR4133 is based on a 64-bit MIPS architecture RISC CPU core that runs at a 266 MHz clock rate and delivers a performance level of 433 million instructions per second, NEC said.

According to its data sheet, the VR4133 includes SDRAM/ROM/Flash memory controllers, dual 10/100 Mbps Ethernet MACs, a hardware-based IPsec security processor, PCI expansion bus, dual serial ports, IrDA interface, real-time clock, and general purpose input/output lines.

Embedded system development using the VR4133 is supported on NEC's development “RockHopper” platform via a plug-in VR4133 processor “personality” module. From the embedded software perspective, a port of MontaVista Linux to the VR4133 is in process (if not already available), and a plain Linux kernel ported to the VR4133 is also available directly from NEC for those preferring the “do-it-yourself” approach.
